12 Signs Your Dog Is Becoming Overheated

Summer Joys and Hidden Dangers

Summer brings sunshine, long walks, and outdoor adventures with our pets. But while warm weather is delightful for us, it can be dangerous for dogs. Unlike humans, who have sweat glands across their bodies, dogs only sweat through their paw pads and nose. Their main cooling mechanism—panting—is far less efficient. This means dogs are at a much higher risk of overheating and heatstroke, which can cause severe damage to the brain, heart, liver, and nervous system in minutes.

Understanding the signs of overheating and knowing how to respond can save your dog’s life.


Signs Your Dog May Be Overheated

Heatstroke is the most serious consequence of overheating. It can happen quickly, even in spring or early summer, before your dog has adapted to warmer temperatures. Watch for these warning signs:

  • Heavy panting or rapid breathing

  • Bright red or dark gums and tongue

  • Excessive drooling

  • Weakness, collapse, or staggering

  • Vomiting or bloody diarrhea

  • Glazed eyes and confusion

  • Seizures or unconsciousness

  • Elevated pulse and heartbeat

  • Excessive thirst

Dogs at higher risk include brachycephalic breeds (flat-faced dogs like bulldogs and pugs), seniors, puppies, overweight pets, and those with chronic health conditions.


What to Do If Your Dog Overheats

If you suspect heatstroke:

  1. Move your dog immediately to a cool, shaded, or air-conditioned area.

  2. Offer small amounts of water—never large gulps at once.

  3. Cool the body with water (not ice-cold), focusing on the head, neck, and under the legs.

  4. Use fans to speed cooling.

  5. Check temperature—if it drops to 104°F, stop cooling to avoid shock.

  6. Seek veterinary care immediately, even if your dog seems better.


Preventing Heatstroke: Smart Summer Habits

  1. Never leave dogs in cars – Temperatures inside vehicles can soar to 120°F in minutes.

  2. Provide constant fresh water – Hydration is critical. Consider filtered water with Waterdrop or Aquasana systems for purity.

  3. Avoid hot pavement – Asphalt can burn paws and radiate heat. Use dog shoes or walk during cooler hours.

  4. Plan activities wisely – Exercise early morning or after sunset. Keep play sessions short in hot weather.

  5. Create cool indoor spaces – Use Austin Air purifiers to maintain clean, cool air indoors.

  6. Emergency preparedness – Keep EcoFlow or Jackery portable power stations ready to run fans, purifiers, or cooling devices during outages.
